Things I would have changed: Use better mounting screws. Make the switches easier to turn. Use actual windage and elevation knobs so that you can make adjustments on the fly instead of having to carry around a screwdriver or a coin to adjust the windage and elevation.

What others should know: I'm not sure if it is just mine or if others have the same flaw but on the windage knob it says you turn the knob clockwise to adjust the windage left. Except when I do that the windage goes right instead of left.
